David Neto 445ce4401d Add operand type for extension instruction number 
This is required to support extended instructions that
have literal numbers as operands.  An example is OpenCL's
vloadn.

The previous code in the assembler assumed that *any* literal
number argument in any part of an OpExtInst must be the name
of the extended instruction.  That's true only for the first
literal number argument.
